yea... that's what I've done. when I drag the header file from the
appkit framework to IB and then the header
for my subclass it works.

I have a controller that's a subclass of NSAnimation.
when I try to import the header to interface builder in order to
instantiate it there I get the following error message:
"Unknown superclass, Iinterface Builder cannot find the superclass
of one of the classes found in this header file."
does anyone know the reason for this and how this can be avoided ?
NSAnimation requires os x tiger. can it be that I'm missing to
adjust a setting in IB appropriately ?
Looking in the class listing in a NIB file in IB, I find that
NSAnimation does not appear among the classes Interface Builder
knows about. As NSAnimation conforms to NSCoding, it should
theoretically be possible to store one in a NIB, but there's no
provision for it now. <http://bugreport.apple.com/> if you want
support to be added.
Adding NSAnimation to the NIB's class tree would not be useful, as
there'd be no way to initialize the animation.
If it were me, I'd allocate and initialize my animation in the
awakeFromNib handler for the owner of the NIB.
